Pressure retention valve DAV for monitoring third-party pressure

The pressure–sustaining valve opens quickly via the control line of the external pressure and closes slowly when the external pressure lowers. So that the control valve can be relieved again after pressurisation (and the main valve closes again), it must be possible to relieve the control line of the external pressure. The pressure of the control line (external pressure) should be within the range of 2 to 16 bar.

Application:
-    To use in drinking water systems (other media after consultation)
-    As an open/shut valve with hydraulic control (e.g. sprinkler systems)
-    Maintaining a network pressure
